Freescale CoreNet Coherency Fabric(CCF) Device Tree Binding

DESCRIPTION

The CoreNet coherency fabric is a fabric-oriented, connectivity infrastructure
that enables the implementation of coherent, multicore systems.

Required properties:

• compatible:

    fsl,corenet1-cf - CoreNet coherency fabric version 1.
    Example chips: T4240, B4860
  
    fsl,corenet2-cf - CoreNet coherency fabric version 2.
    Example chips: P5040, P5020, P4080, P3041, P2041
  
    fsl,corenet-cf - Used to represent the common registers
    between CCF version 1 and CCF version 2.  This compatible
    is retained for compatibility reasons, as it was already
    used for both CCF version 1 chips and CCF version 2
    chips.  It should be specified after either
    "fsl,corenet1-cf" or "fsl,corenet2-cf".
  

• reg:

    A standard property. Represents the CCF registers.
  

• interrupts:

    Interrupt mapping for CCF error interrupt.
  

• fsl,ccf-num-csdids:

    Specifies the number of Coherency Subdomain ID Port Mapping
    Registers that are supported by the CCF.
  

• fsl,ccf-num-snoopids:

    Specifies the number of Snoop ID Port Mapping Registers that
    are supported by CCF.
  

Example:

corenet-cf@18000 {
    compatible = "fsl,corenet2-cf", "fsl,corenet-cf";
    reg = <0x18000 0x1000>;
    interrupts = <16 2 1 31>;
    fsl,ccf-num-csdids = <32>;
    fsl,ccf-num-snoopids = <32>;
};
